Beginning her book tour with a bang, Jane Fonda says sitting at an anti-aircraft gun during her 1972 visit to North Vietnam was “the largest lapse of judgment that I can even imagine.” However, Fonda also says she didn’t regret other aspects of the trip, such as meeting American POWs or “making broadcasts on Radio Hanoi.” In an interview with 60 Minutes in support of her new memoir, Jane Fonda: My Life So Far, Fonda says “Our government was lying to us and men were dying because of it, and I felt I had to do anything that I could to expose the lies and help end the war,” according to an Associated Press wire story. The interview will air Sunday.
